IMPROVEMENT IN LOCOMOTIVES.

Specification forming part of Letters Patent No. 188,971, dated March27, 1877; application filed I January 16, 1877.

To all whom it may concern:

Be it known that I, THOMAS T. V. SMITH, of Yarmouth, Nova Scotia, haveinvented certain new and useful Improvements in L0- comotives, of whichthe following is a specification:

The nature of my invention consists in the peculiar construction andarrangement of a supporting -frame for a locomotive engine,

the'supporting-frame consisting of round bars attached in front to thecylinder-supports, and at the rear to the fire-box and bufferbeam, theobject being to simplify the construction so as to place it within theskill of the most ordinary mechanic, so that the parts may be detachedor connected without the aid of a highly-skilled mechanic.

Figure 1 is an elevation, one of the wheels being removed to show thehousing more clearly. Fig. 2 is a part front elevation and part section.

As the boiler, cylinder, and fire-box are made in the ordinary mannerthey require no description. The frame is made as follows: A A are tworound rods, of iron or steel, extending from the cylinder-supports infront of the engine to the buffer-beam O, at the rear of the engine, andbeing attached to the fire box by a saddle-piece, D, Fig. 1.

The lower part of the frame also consists of round bars, but not in asingle piece like the upper ones, the part A extends from thecylinder-support to the front of the first housing, while the part Aextends from the rear of the first housing to the front of the secondhousing, and the part A extends from the rear of the second housing tothe bufferbeam 0.

The housing has two side pieces, E and E, which are slipped onto theupper rod A of the frame, and are fastened to it by means of keys orpins.

The lower rods A A A are fastened into these side pieces E E, the endsof the rods simply passing through the side pieces E E, and stoppingeven with the inner face of the same.

K K represent the journal-boxes. H is a short rod, which serves toconnect the lower ends of the side pieces E E, and thus complete thehousing. This may be fastened by screws or keys.

From the above it may be seen that to remove an axle [have only to takeout the short bolt H. This leaves the boxes and axles free. By thisstyle of frame I secure great simplicity, cheapness, and strength.

I claim as my invention 1. The combination of the rods A A A A with thebuffer-beam O, fire-box, and cylinder-supports, all constructedsubstantially as described, and for the purpose set forth.

2. The combination of the rods A A A A, with the sides E E, of thehousings and the rod H, all constructed substantially as described, andfor the purpose set forth.
